    Tingling Teeth!

    Hi all,Question for all the peopple out there. I dive on an Inspiration Vision and did my Mod 2 course in Malin Head, Ireland (best wreck diving in the world :D). I had no trimix qualification prior to that.

    Since I started diving trimix, I have noticed that I seem to get tingling teeth after a dive. This usully happens about 5-15 minutes after I surface and vansihes after two or three minutes. First time it happened was on my course but seems to happen on every trimix dive I do on the rebreather. Never had this when I dived open circuit or used air as the dil.

    I have suffered the odd bend before (two skin bends and some elbow pain ... all treated and got the all clear after) but they were on profiles where I really pushed the limits. Stupid dives that I look back on these days and think "why the F*&% did I do that and thank god I'm still here". I now dive much more conservatively using a combination of the Vision (GF 20/85), my VR3 and V-planner and always work to the most conservative of the three with the other two as a back-up. As a result of this, I tend to pad my stops.T

    his tingling in my teeth doesn't really worry me too much but I'm curious about it. I think I'm just having a reaction to the helium but I would be curious to hear what anyone else thinks. The other option is that it is micro-bubbles but the fact that I only get it on trimix dives is funny. I have run much longer dives with much more deco on air dil than I have done to date on trimix.

    Any ideas welcome (unless you suggest I give up diving in which case ... ).

    Have you had any dental work recently? For a long time after I had some old fillings replaced I had pain on ascent and for 5-10min after the dive. I suppose some gas must have been migrating through small channels in the filling material under pressure and then causing a reverse squeeze on ascent. Helium is a significantly smaller molecule than nitrogen so possibly it's easier to migrate?

    I'm not a dentist though.

    Is it possible that you are feeling sinus pressure in the roof of your mouth?

    Is it possible that one of your current fillings is starting to decay, thereby letting gas under it? I'm under the impression those things don't last forever.
